I think the art style of the world map was much nicer in the E3 demo. I like the drawn style more. I feel like a drawn cartography style map goes well with the exploration themes. For the same reason, I would prefer the character and ship to be represented by a generic explorer and ship figurine, perhaps with a base on it, so it looks like a real map with figurines standing on it. I am thinking in the style a strategical map you would see in war rooms. You know, the ones where they push there little army men across them to illustrate army movements. Having the ship be represented by a non-rotating figurine would also solve the problem I have with the ship movement feeling kind of wonky. A ship just shouldn't turn like that and I would prefer if it didn't turn at all.
I also don't particularly like the little pickups. It feels weird that my party would go for a detour lasting several days, to pick up a bunch of mushrooms. If there are unique items, i think they should be presented in a vignette, where you must pass some challenge to get the item. This would make it feel like a worthwhile adventure, but be significantly easier to make than designing an entire area. It could, for example, be an abandoned temple filled with traps with a cool little item at the end, if you can pass the skill checks. These can be more or less involved depending on the item.
I do like the idea of a world map, though. Makes the world feel a lot larger and will be fun to explore.
